Nothing written about this breed yet. The hereditary risks are sourced — read those.
Breed-level information from The Cat API. It describes the Neva Masquerade in general; any individual animal can differ.
No breed-specific health panel has been written up for the Neva Masquerade on this platform yet. That is a gap in our records, not a clean bill of health — ask the breeder which hereditary conditions their lines are tested for, and ask to see the results for both parents, dated and from a named laboratory.
